When a user wants to register to a new XS server, they to first manually clear the previous registration details (if present).  Then they have to create new registration even if they are returning back to an XS server where their laptop has been registered before. For non-XO laptops, every new registration changes the random serial number of the laptop and serial number is used in backup url and backup paths for that laptop in the XS server. Hence registering multiple times with the same XS server leads to unnecessary change in backup path on non-XO laptops.

Also from the various field reports where a user (generally a teacher) has to register to multiple XS servers on move, it becomes difficult to keep clearing the registration details manually. ([https://bugs.sugarlabs.org/ticket/362 one such report here].
